Bosch lithium-ion battery (for Bosch 36 volt system, 4.0 Ah, in a box) | for Bosch 36 volt system, 4.0 Ah, in a box

very happy with battery

Expensive but very good performance, my previous 4ah battery lasted more than 7 years before its run time in my lawnmower has started to decline. This is the replacement for it and my old one will remain as a backup.

Back to mowing the lawn.

if you want a durable battery buy one of these Bosch units. they are well made and last well

I purchased this 4Ah battery to replace the lower capacity version supplied with the cordless lawn mower which was found to have failed when I tried it for the first time after storage over the winter months. I can now cut the grass twice between recharges which was not possible with the previous battery, even when it was new and at full capacity.

Great battery life, does the whole job on one charge, with more juice spare, that would normally take 2 batteries to do. And on thicker grass too.All you gardening Dads out there, tell the kids you no longer want socks/handkerchiefs/underpants for Xmas or birthdays, but want one of these instead.Expensive but worth it.

My battery for Bosch Rotak 37i had failed after 10 yrs. Searched for replacement and ordered this after reading all the reviews.Excellent delivery arrived within 24 hrs.My product notice was marked upgrade. The battery I received was red not green and the code matched a cool pac Bosch battery. Which I understand is an upgrade.It fits my charger and fits my mower and it is a good product as far as I can tell. I have tried to leave seller feedback but Amazon site is not letting me. Very pleased with the seller.I am so far happy with this product and hope it lasts as long as the original.

Wish if the life was more

Senza dubbio si nota la durata in più che offrono i 4Ah rispetto ai 2,6Ah.

Ürün orjinal ve kalitesi şark süresi gayet iyi

J’ai acheté cette batterie car j’ai déjà la même mais l’autonomie de cette batterie ne me permettait pas de tondre 1000 m2 de terrain en 1 seule fois, j’en ai donc acheté 1 autre et les 2 batteries me permettent de tondre à présent en 1 seule fois ma superficie de terrain. Très bonne qualité et bon rapport qualité/prix.

Seit einigen Jahren benutzte ich 3 Akkus je 36 V 2.6 Ah am Rotak 43.Ein Akku ist nach über 10 Jahren Nutzung ausgefallen und nun hab ich von von den neuen Akkus 36 V 4,0 Ah erfahren.Dieser Akku ist leistungsfähiger und läßt sich problemlos mit meinen vorhandenen Schnell-ladegerät aufladen.Leider ist ein Plastikteil von der Höhenverstellung gebrochen, aber durch meine Notreparatur vor einigen Jahren läuft der Rotak noch einwandfrei.

Genuine Bosch. Great quality. Well worth it over the Chinese copies when Amazon has them on sale.
